title: Effects of lexical stress in auditory word recognition.
abstract: Although research examining the use of prosodic information in the processing of spoken words has increased in recent years, results from these studies have been inconclusive. The present series of experiments systematically examines the importance of one prosodic variable (lexical stress) in the recognition of isolated spoken words. Data collected in an identification task suggest that segmental information may be more heavily relied upon when appropriate lexical stress information is not available. Results of subsequent reaction time experiments support the hypothesis that lexical stress influences the processing of auditorily presented words. In three shadowing experiments, correctly stressed items were produced faster than incorrectly stressed items, and in a lexical decision experiment, correctly stressed words were classified faster than incorrectly stressed words. Thus, this work provides evidence across several experimental tasks for the use of lexical stress information in the processing of spoken words. Moreover, the data suggest that lexical stress should be an important aspect of the representation of words in an interactive model of auditory word recognition.
